The patrol says the 17-year-old failed to negotiate a sharp turn in the road and continued straight. He tried to get back on the road, but overcorrected, causing the car to roll through a fence and down an embankment. The car landed on its top in an irrigation ditch.

The patrol tells The Billings Gazette (http://bit.ly/1yq88Ju ) the driver was trapped in the vehicle, but the younger boy was able to get out. He was taken to the hospital in Glasgow.
